Embodiment 1

[0030] figure 1 This is a flowchart of a method for acquiring pre-alarm data provided in Embodiment 1 of the present invention. This embodiment can be applied to the case of acquiring pre-data before an event time node. Setting data, the method can be performed by a pre-data acquisition device, the device can be implemented by hardware and / or software, and generally can be integrated in electronic equipment, the method specifically includes:

[0031] Step 110: Set a data time point for the full amount of data, and send the full amount of data to the relay data stream;

[0032] Among them, preset equipment will be installed on the vehicle to collect data during the operation of the vehicle. These data are preset, which can include positioning, speed, acceleration, vehicle gear, usage of lights, and obstacles around the vehicle. Information, the preset device may be a vehicle safety device. When there is abnormal data in the data monitored by the vehicle safety device and the c...

Embodiment 2

[0047] figure 2 It is a flowchart of a method for obtaining pre-data provided in Embodiment 2 of the present invention. This embodiment is further refined on the basis of the above technical solution, and the judging of the data type of the relay data may include: judging the data type of the relay data. Whether the relay data contains an alarm code field; if it contains the alarm code field, the relay data is the alarm data; if it does not contain the alarm code field, the relay data is the Full data. Specifically, the method includes:

[0048] Step 210: Set a data time point for the full amount of data, and send the full amount of data to the relay data stream;

[0049] Step 220, if the obtained alarm data is preset alarm data of a preset type, store the preset alarm data in a preset cache;

[0050] Step 230: Set a data time point for the preset alarm data, and send the alarm data to the relay data stream;

[0051] Step 240, if the accumulated data time point obtained a...

Embodiment 3

[0060] image 3 This is a flowchart of a method for obtaining pre-data provided in Embodiment 3 of the present invention. This embodiment is further refined on the basis of the above technical solution. If the relay data is the full amount of data, in the Searching for the preset alarm data corresponding to the relay data in the preset cache includes: acquiring preset device information from the full amount of data; The preset alarm data of the preset device information. Specifically, the method includes:

[0061] Step 310: Set a data time point for the full amount of data, and send the full amount of data to the relay data stream;

[0062] Step 320, if the obtained alarm data is preset alarm data of a preset type, store the preset alarm data in a preset cache;

[0063] Step 330: Set a data time point for the preset alarm data, and send the alarm data to the relay data stream;

[0064] Step 340: If the data time point of the relay data is accumulated and the preset time th...

Abstract

The present application relates to a pre-data acquisition method, device, device and storage medium, the method comprising: setting data time points for the full amount of data, sending the full amount of data to the relay data stream; if the obtained alarm data is a preset type The preset alarm data, store the preset alarm data in the preset cache; set the data time point for the preset alarm data, and send the alarm data to the relay data stream; if the data time point of the relay data accumulates the preset time The time point of the accumulated data obtained after the threshold is earlier than the current time, and the data type of the relay data is judged; if the relay data is the full amount of data, and all the data corresponding to the relay data are found in the preset cache The preset alarm data, storing the full amount of data whose data time point is within the lead time range of the corresponding preset alarm data. The technical solution of the present application can improve the lead time acquisition efficiency.

Description

technical field [0001] The present invention relates to the technical field of data processing, and in particular, to a method, device, device and storage medium for acquiring pre-data. Background technique [0002] In IoT data stream processing, it is possible to encounter events that pass through the current time point and trace back the stream data of the previous event at the time node of this event. For example, when the vehicle safety device monitors the vehicle safety, and a vehicle alarm event occurs, the relevant data situation of a period of time before the alarm event can be traced, so as to restore the situation when the alarm occurred. [0003] In the existing data acquisition method, the data of the device is usually flowed into the database, and then the pre-data of the device at the event time node is obtained by querying the database. However, this method is relatively inefficient in querying data in the case of a large amount of data, and cannot obtain pre...
